Japan and the United States have reportedly agreed to revise their bilateral defense cooperation guidelines by the end of 2014, in a bid to cope with changing security environment.
The decision which was the first time in 17 years, was made during the Japan-US 'two-plus-two' summit between Japanese Foreign Minister Fumio Kishida and Defense Minister Itsunori Onodera and their US counterparts John Kerry and Chuck Hagel.
The two countries also agreed to move part of US military personnel from Japan's Okinawa to Guam from the first half of the 2020s to ease the burden of holding bulk of US bases in Japan.
